How to refer a JS library file and call its functions from both Client and Server side scripts?

[Ramesh Babu1]

I want to put my common code in a library file and access it across Service Now application in both Client and Server side scripts.

Suppose, I have this common function in an external file. I want to call this from both Client and Server scripts.

function truncateString(input){
    var output = input;
    if(input && input.length>10)
    {
        output = input.substring(0,10);
        output += '...';
    }
    return output;
}

Please let me know.

You need to use script includes functionality.

you can call script include from client and server side scripts.

Hi

You can put your functions in Script Includes and mark the field "Client callable" as active (see screenshot below):

You then can call the functions inside of your scripts like:

var myScriptInclude = new DirkTest;

myScriptInclude.test();

Have fun!

If that answered your question, let me know and mark my answer as correct and helpful,please-

Hi Dirk,

Thanks for the response.

I want to call the function which is in an External Library. I want to refer the library first in ServiceNow and then call its function from anywhere in ServiceNow.

Thanks,
Ramesh
